Introduction Research in the area of ecofriendly and biodegradable packaging films is currently of prime interest due to their advantages in protecting foodstuffs and reducing environmental pollution by reducing petroleum-based plastics packaging materials currently in use.
The functional properties of chitosan films are improved when chitosan is combined with other film-forming materials.
Experimental Section Materials Chitosan (degree of deacetylation of 85%) with molecular weight of about 106 was purchased from Jinan haidebei Marine Bioengineering Co., Ltd.

The characterization results present information to determine the techniques and materials used for the ceramic production during the medieval and after medieval period.
The archaeological evidences such as kiln and kiln materials to be found in 2001 have been point out the existence of ceramic production in that region.
Results were used to extract information about processing condition, materials used during the ceramic production.

Besides, polythiophene/metal oxide, polypyrrole/SnO2[8], CuPc/H2PtCl6 and other hybrid materials emerged gradually.
For H2S gas sensors, searching for better sensitive materials is a good direction.
There are many factors to contribute to the attenuation of response, including dust, water vapor and other materials adsorbed to the surface of the film, which affected the film’s adsorption of gas molecules.
